Report of Solar Geophysical Activity

 

Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 7 Issued at 2200Z on 07 Jan 2016

IA.  Analysis of Solar Active Regions and Activity from 06/2100Z to
07/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
07/0617Z from Region 2480 (N03E58). There are currently 4 numbered
sunspot regions on the disk.
IA.  Analysis of Solar Active Regions and Activity from 01/2100Z to
02/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M2 event observed at
02/0011Z from Region 2473 (S21W89). There are currently 4 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares and a slight chance for an X-class flare on
day one (03 Jan) and expected to be very low with a chance for a C-class
flares on days two and three (04 Jan, 05 Jan).
IB.  Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares and a slight chance for an M-class
flare on days one, two, and three (08 Jan, 09 Jan, 10 Jan).

IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
632 km/s at 06/2251Z. Total IMF reached 8 nT at 06/2333Z. The maximum
southward component of Bz reached -6 nT at 07/0056Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 5126 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (08 Jan) and quiet levels
on days two and three (09 Jan, 10 Jan).
